Re: VLF: 1.6 Hz from Kiruna?

[VIGILANT Luis Fernández <luis@vigilant.es>]

Hi David, Clemens, Markus. ELF ! :-O

I have searched about Kiruna observatory and found the page which shows the magnetic pulsations

daily. There is really an interesting signal at about 1.6Hz during March 2015 which can't be seen

in other months/years http://www2.irf.se/maggraphs/puls.php

A test would be quite interesting David. Do you mean you can transmit actually with your Tesla system

and leave a trace at Kiruna at >2000Km ? Or that from march 2015 was an exceptional achievement

and unique event ?

At minimum this is fascinating David. A demonstration would be very interesting. Are you able to set

the system on Tx ?

Hi Clemens, I don't understand that sort of stuff, and I just judge the antenna on its 'on air' receive and transmit performance. It sounds

like 'Marconi' technology type of 'logic', and I'm very doubtful it applies to the VLF Tesla antenna technology.

It's essential when doing 'Tesla', everything Marconi appears irrelevant, and best 'forgotten'. This causes technical disputes, and so it's

best to wait and see how it performs on Long Waves as a transmitting antenna.

Another interesting thing noticed after ELF transmissions (at 1.6 Hz), are very long delayed echoes that last for extremely long periods. The signals also get 'distorted', and the timings are also changed by the ELF propagation. Local 'mixing' with mains hums also occurs at the receiver locale, creating 'spurious' by products. This is all so different to any other type of radio. These strange 'effects' occur below 5 Hz, but the 'sprogs' spread up to 200 Hz.

These strange propagation effects may not occur at 'normal' frequencies, so that's one reason to investigate the Tesla method on ordinary VLF and Long Wave (LF).

I realise this will be 'weird' to most, and it's something that was 'forgotten' over 100 years ago, when Tesla's work was 'written out of history'. The Tesla stuff found on the web is missing much vital information, and without that, it is incomplete and does not work. I am referring to Tesla's power by wireless system, which is a VLF one.

With very kind regards, David.

Hi David,
>>Maybe you can disclose at least the the 3dB BW of this kind of antenna?
>Hi Clemens, I'm not sure I understand your question.
The 3 dB bandwidth is f0/Q and  Q is defined as X/R
where X is the reactance of the inductor and the capacitor at the
resonant frequency.
The lossless-Q of a small antenna is a useful academic quantity, and is
the reactance divided by the radiation-resistance.  It gives the maximum
theoretical Q for any given small antenna, and then the actual Q can be
measured on the real antenna.  The radiation efficiency is the lossless Q
divided by the actual Q, by the equations:
Qlossless = X/Rrad,
Qactual = X/(Rrad+Rloss),
Qactual/Qlossless = Rrad/(Rrad+Rloss) = radiation efficiency.
An interesting limit for small antennas is the minimum lossless Q that can
be achieved, and was derived by Chu in 1948 from only the frequency and
the size of the antenna.
